MW2 killstreak count towards other killstreak???

how come when im playing mw2 if i get up to my pavelow only sometimes the pavelows kills count towards getting my next killstreak???

i know care packages dont count im not using those

is ur pavelow ur last killstreak? so if u haven't died and ur pavelow is still killing ppl ur on the same killstreak, so u get nothingLightColor

ok heres the thing

AFTER you call in the pavelow if you get the next kill before your pavelow does then the pavelow kills count towards your current killstreaks,

IF the pavelow gets the next kill before you then the pavelow kills will not count towards your killstreaks

Is there a reason for that? Seems a bit pointless.SaltyMeatballs
